Description

Second calcined sub fused alumina sand, its crystalline is good, the performance is more stable, can be widely used to produce various shaped refractory products. It is a new type of high-grade refractory material to replace white fused alumina and dense fused alumina. AL2O3 ≥ *8.5% Fe2O3 ≤ 0.*5% TiO2 ≤ 0.8% SiO2 ≤ 0.4% C ≤ 0.1% bulk density of 3.9 Second calcined sub fused alumina powder is heat treated from pickling sub fused alumina powder and reduced Tc, Fe2O3 and other astable factors. Its stability and color are more closer to white fused alumina. AL2O3 ≥ *8% Fe2O3 ≤ 0.*5% TiO2 ≤ 0.8% SiO2 ≤ 0.*5% C ≤ 0.1% Bulk Density 3.*6 Pickling refined sub fused alumina sand can be widely used in fused alumina castables and other unshaped material and light calcined alumina refractory products. AL2O3≥*7.5% Fe2O3≤0.3% TiO2≤1% SiO2≤0.5% C ≤ 0.*5% Bulk density 3.*4 Pickling refined sub fused alumina powder can be widely used to produce various shaped and unshaped refractory products, with small expansion and high density. It is a new refractory material to replace white fused alumina and dense fused alumina. AL2O3≥*8% Fe2O3≤0.2% TiO2≤1% SiO2≤0.5% Size: **0 mesh, **0 mesh, **0 mesh, **0 mesh, **5mesh
